The PWC IP found in the RZ/V2M family of chips fits the Multi-Function
Device (MFD) model quite well, and comes with the below capabilities:
* external power supply on/off sequence generation
* on/off signal generation for the LPDDR4 core power supply (LPVDD)
* key input signals processing
* general-purpose output pins

Version 4 of this series basically just moves the dt-bindings
file under Documentation/devicetree/bindings/soc/renesas.

Thanks,
Fab
